Description
Further Information
The Mayfair is a cartridge type centrifugal extractor fan. It is fitted with a maintenance free
rubber mounted motor. The cartridge system permits the fan to be removed from the wall or
ceiling without disturbing the ductile wiring or wall fittings. The facility greatly simplifies
maintenance and cleaning procedures.
On new build and renovation projects the Mayfair 2000 fan permits all the installation work to
be carried out in advance of the fan being fitted, thereby reducing the possibility of theft or
damage. The Mayfair 2000 range is available with a wider range of features than any other
extractor fan. It is a high quality product and will give many years of reliable service.
APPLICATION

MCC 070B, MCC 100B, MCC 140B.
Adjustable condensation control turns fan on automatically when
humidity reaches a preset level and off when humidity drops
below that level. When not operating on humidity the fan functions
at the single speed with time delay. Manual operation is normally
via the light switch.
Twin Speed
with time delay/
condensation control

with additional
pull-cord boost
MCT 070B, MCT 100B
Adjustable condensation control switches onto slow speed
when humidity reaches a preset level and off when humidity drops
below that level. The fan can be switched onto high speed (boost)
using a remote switch (normally via a light switch). When the high
speed is turned off an adjustable timer keeps the fan running on
high speed for a preset time. Alternatively the fan can be switched
on to high speed using the integral pullcord switch. The pullcord
switch works independently from the remote switch. When either
the remote switch or pullcord switch is operated a red indicator is
illuminated.

SURFACE MOUNTED
There are two types of surface mounting boxes. Fan models 070 and 100 require type MAY
504A and models 140 require type FLA 106A.
For installation on either wall or ceiling, follow the same procedures as frame mounted fans
with the exception that the discharge duct needs to be flush with the surface of the inside wall
or ceiling, to meet up with the discharge outlet of the surface mounting box.
MIR 070B, MIR 100B, MIR 140B.
These fans are operated by a passive infra-red sensor detecting
movement. The range of the sensor is about 5 metres with an
operational arc of 15 degrees from the centre of the sensor. The
control unit features an adjustable timer. This allows the fan to run
for a preset time after the last movement within the range of the
sensor has been detected. Important: Passive infra red operated
fans must not be installed above a heater or radiator.
Please refer to pages 9/10 for relevant wiring diagrams. When fitting the 070 and 100 models
into surface mounting box (MAY 504A) it is necessary to remove the fan motor cover. To do
this, remove the motor cover retaining screw. Ease front cover clear of the two clips. The motor
cover may be discarded. It is not necessary to remove the motor cover from the 140 models to
fit them into their surface mounting box (FLA 106A).
To fit the fan into the surface mounting box, first remove it’s front cover. This is retained by a
screw on the bottom edge. Enter the electrical contact pins and discharge spigot into their
sockets and push gently into position. Retain the fan with four 6mm screws supplied. Refit
front cover.

WALL MOUNTED
CEILING MOUNTED
In the chosen position (as high on the wall as possible) cut a hole through the wall to take a
100mm duct for the fan discharge. This should slope downwards towards the outside to
allow for condensation drainage.
Select a suitable position on ceiling for fan. Ensure that the chosen position is between and
square to the roof joists. Using the building-in frame as a template, mark and cut out the
square hole to fit the frame into. Cut and fit two noggins to fit between the joists. Position them
alongside the frame aperture so they will support the frame when it is in position. Fit the frame
into position ensuring the front edge is flush with the ceiling surface. Secure firmly by screwing
through the holes in the side of the frame into the joists or noggins.
When this is done, position the building-in frame with the discharge outlet at the top right
over the duct hole. Mark around the frame and cut an aperture to take the frame and fan. It
is important that the front edge of the frame is flush with the surface of the wall.
If fitting in a solid wall the aperture should be at least 115mm deep. If installing in a cavity
wall with loose thermal insulation you will need to make a cavity liner.
When all the cutting is done, grout the frame into position making sure that the front edge of
the frame is flush with the wall. When the frame is in position, fit the discharge duct into
position from the outside and trim to length. Before grouting into position, seal the duct to
the building-in frame spigot. When duct is in position fit discharge grille (ANC 413D).
While fitting the building-in frame, provision must be made for the power supply cable.
Relevant wiring diagrams are on pages 9/10.
To fit the fan, first remove the front cover, this is retained by a screw on the bottom edge.
Enter the electrical contact pins and discharge into their sockets and push gently into
position. Retain fan with the four 6mm screws supplied. Refit front cover.
The discharge from the fan may be ducted through a roof cowl or through the eaves. If ducting
through a cowl, provision must be made for condensation drainage. A condensation trap can
be made from flexible ducting as illustrated or you may use a purpose made product (ANC
582A).
If discharge is to exit through the eaves, the duct must slope downwards towards the outside
to allow for condensation drainage. To ensure maximum efficiency from the fan, flexible ducting
and bends must be kept to a minimum.
Please refer to pages 9/10 for relevant wiring diagrams.
To fit the fan first remove the front cover. This is retained by a screw on the bottom edge. Enter
the electrical contact pins and discharge into their sockets and push gently into position.
Retain fan with the four 6mm screws supplied and refit the front cover.
